1.How would you make 1 mL of a 1 to 25 dilution of yeast crude extract?
2. Enzyme activity measures:
A)The number of polypeptide molecules
B)The number of substrate molecule
C)The energy used in the reaction
D)The rate at which substrate is processed by the enzyme
1.How would you make 1 mL of a 1 to 25 dilution of yeast crude extract?...
How would you make 1 mL of a 1 to 25 dilution of yeast crude extract? Be specific.
How would you make 120 mL of a 1 to 25 dilution of a yeast extract? I'm really not understanding this process so steps/explanations would be nice. Thanks.
1. You want to prepare a 1:50 dilution of your protein extract in a total volume of 1000 uL. You will need ___ uL of protein extract and ___ uL of water. 2. You are provided with a solution of BSA that is 100 ug/mL and make a 10-2 dilution? What is the resulting concentration of the DILUTED BSA? 3. Which of the following statements about enzymes is true? Select one: a. Enzymes increase the rate of a chemical reaction...
You were given a 25 mg/mL stock of enzyme A, how would you use a serial dilution series to make a 5 ug/mL stock? What is the final dilution factor?
you’re asked to make 380 ml of a 1/20 dilution. how many ml of diluent will be used
Explain how you would make a 1/1000 dilution of a bacterial suspension if you only had 3 ml aliquots of BHI broth (diluent) available. What size pipetman will you need to use to make this dilution?
Show how you would make up a 10-5 dilution, given 1 ml pipets and 99ml water blanks. Your original samples is undiluted milk.
Part A - Overview of enzyme structure and enzymatic reactions Enzymes are large globular proteins. Much of their three dimensional shape is the result of interactions between the R (variable) groups of their amino acids. The active site is the portion of the enzyme that will interact with the substrate the molecule that the enzyme acts upon. The nature and arrangement of amino acids in the active site make each enzyme specific to a substrate and to the reaction it...
Please show how to do these enumeration questions by showing the work. What is the dilution factor if you add 625 µL of culture to 4.375 mL of dilution medium? You count the 10-3 dilution of a yeast suspension using the 1/25 mm2 boxes : you find 45 cells in box 1, 15 cells in box 2, 42 cells in box 3, 23 cells in box 4, and 26 cells in box 5. a) What is the original concentration of...
b. 1 ml 1ml 「-I Final dilution 4(1 point) This represents a serial dilution to determine viable bacterial counts. Indicate the final dilutions in each of the two tubes. Note that two different volumes of the cells intube #2 are plated onto agar plates A and B. Indicate the dilution factor that will be used to report the original cell concentration on a per mL basis. 1 ml 1 ml Final dilution in Tube #1 = Final dilution in Tube...
